NITED HENRY P. FEISTER, OF PHILADELPHIA, PENNSYLVANIA.

MULTlCOLOR-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 273,672, dated March 6,1883. Application filed May 16, 1%8'2. (No model.)

To all whom it may concern Be it known that I, HENRY P. FEISTER, of thecity and county ofPhiladelphia, and State of Pennsylvania, have inventeda new and useful Improvement in Hulticolor-lrinting Machines, of whichthe following is a specification.

My invention has reference to printingpresses; and it consists in adouble frisket, through which the continuous web of paperis passed;further, in two rotating and oscillating heads, one of which carries thetype and the other the make-ready; further, in combining with theoscillating type-head an inkingwheel adapted to ink type on the headwith a different color at each oscillation,'and in many details ofconstructien, all of which are fully set forth in the followingspecification, and shown in the accompanying drawings, which form partthereof.

The object of this invention is to do what is technically known ascolor-printing bycausing the paper to be held stationary while thedifferent colors are printed thereon by the type-forms, which areautomatically changed to insure a perfect register, and prevent allaccidental lapping of the colors, as is sometimes the case when thepaper is handled two or more times before the print is completed.

This invention is particularly adapted to print book-backs for allnanacsand pamphlets generally, and would be used in connection with the bookprinting and binding machine granted to me by Patent No. 256,662, datedApril 18, 1882.

In the drawings, Figure 1 is a sectional elevation of a color-printingpress embodying my invention. Fig. 2 is an elevation of same. Fig. 3 isan elevation of the frisket, and Fi 4 is a side view of main cam-wheels.

A is the frame of the machine.

B is the main shaft, and carries the two camwheels B, provided withcam-grooves I) b, and also the fast and loose pulleys B B and spurwheel0.

C G are the two oscillating heads, one of which, 0, carries the type 0and the other, or O, the make-ready pads (J These heads are madepolygonal, as shown, and may have as many faces as desired, each of saidfaces corresponding to a color. Each of the colorblocks 0 has its ownmake-ready C so that in printing not only is perfect registrationattained, but also the proper and best impression is obtained. Theseheads (J G are respectively pivoted orjournaled to arms D I) at c c, andthese arms are loosely hinged to their respective shafts E E. Each ofsaid arms is provided with a friction-roller, d, which works in thecam-grooves I) Z) of wheels B, which cam-grooves are adapted to draw thetwo heads 0 0 together, hold them in contact for an instant oftime, thenseparate them and hold them away from each other a short interval oftime, then force them together again, and so on continuously, said headsmaking two oscillations for every revolution of the cam-wheels B.Whilethese heads are being oscillated apart they are intermittentlyrotated, so as to bring a fresh color-block and make-ready C in printingposition by means of the pins U on the revolving disks U, working inslots or grooves O in said heads. These disks U should revolve twice asfast as the cam-wheels B. They are rotated by mitergears V, shafts V,miter-gears \V, shafts E E, and spur-wheels e e c 0 but I do not limitmyself to this mechanism, as there are many ways of accomplishing thesame result. The disks U are carried by arms I) D, and do not changetheir relative position with respect to their own heads 0 O. Arrangedbetween said heads is my improved frisket, which consists of two plates,I, provided with one or more perforations, I, through which the typeprints, supported very close to each other by frames J, and betweenwhich the paper to be printed is fed, as shown in Figs. 1 and 3. Ifdesired, the ends of the parts I may be curved outward, as at t, toprevent any possibility of the paper catching. The color-blocks 0 enterthe apertures in one plate I, and the make ready blocks 0 entertheapertures in the other plate I, as shown.

The rollofpaper Kis supported upon an axle, K, and the web It fedbetween tension-rollers L, then is intermittently fed to the frisket bythe adjustable feed-disks M, set two and two, having their sidesnotched, and being adjusted by slots mand bolts m, by which any desiredlength of sheet may be fed. This feedis fully described and claimed inthe aforementioned patent granted to me. Hence in this application I donot claim it, encept in combination.

These disks are adapted to make a half-revolution after the heads C havemade one revolution upon their axes c a. After the paper passes throughthe frisket it is fed between rollers N to the knife P, which isactuated by a crank, P, rod P and cam R on shaft B.

After the paper is cut it falls onto the fly-frame- Q, which is actuatedby the rod Q and cam R to lay said printed paper upon the table B. Anyother suitable mechanism may he used to operate the knife and fly-frame.When the head 0 is moved away from the frisket by the part b of thecam-wheel B the pin U enters a curved groove, 0 in said head and quicklyturns it to the proper position to bring the next color-block intoposition for printing. After turning said head the pin moves on in saidgroove, which is concentric with the axis of wheel or disk U. Hence thepin then acts to steady the head. The moment the head is turned a sixthor an eighth of a revolution the next color-block 0 reaches theinking-wheel, as shown in dotted lines, Fig. 1. The inkingwheel is fastto a shaft, T, with which it revolves, and is provided with as many setsof color-rolls t as there are colorblocks and these inking-rolls t areguided by rails S S, the latter of which are straight, as shown, so asto guide the inking-rolls in. a straight line to ink the color-block.These straight guides S may be adjusted by slots 8 and bolts 8, or byany other means. If the head 0 has six color-blocks 0 then with everyoscillation of the head the inking-wheel rotates one-sixth of arevolution, so as to run one set of color-rolls 15 across the face ofthe color-block corresponding to said color, and when it is at rest andunder action of the concentric part b of the cam-wheel B, this inkingwheel may be intermittently actuated by ratchet wheel t, pawl T, cam Tand roller T or other suitable mechanism.

The operation is as follows: As the shaft B is rotated the cam -wheels Bforce the heads 0 O apart, and during such movement the pins U cause apartial rotation of the said heads, bringing a fresh set of color-blocksand make-readies into printing position. At the end of the outward throwof the heads the head 0, containing the type or color-blocks O, restsagainst the inking-wheel frame. At this instant one set ofinking-rollers t is caused to pass from one side of the guide S to theother, being guided upon the flat guides S over the face of the type.The inking-wheel then ceases to rotate, and is in position to ink thenext color-block or type with another colored ink. By this means eachcolor-block has its own particular inking-rolls, so as not to mix colors5 but, if desired, where there are a duplicate set of color-blocks theremay only be one-half the number of inking-rollers. As the cam-wheels Bstill rotate the heads are drawn together and print upon the paper k,held in 6 the double frisket I. This operationis repeated until all ofthe color-blocks have printed. Then the feed wheels or disks M feed thepaper along through the frisket, and as the next printing action goes onthe knife P cuts the printed part 011', and it falls upon the flyframe Qand is laid upon the table B.

By the use of the double frisket and oscillating printing-head, adaptedto intermittent rotation, I am enabled to print two or more colorswithout moving the paper, thereby insuring the most perfect register.The adjustable guide S regulates the pressure of the inking-rollers uponthe color-blocks. I do not limitmyself to the construction shown, as itmay be modified in many ways.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Inaprinting-press, two oscillatingheads. one of which is providedwith a series of forms of type and the other with correspondingmake-readies, in combination with automatic mechanism, substantially asdescribed, to oscillate said heads to and from each other, andmechanism, substantially as described, to automatically and successivelybring said typeforms and their corresponding makerreadies into printingregister.

2. In a printing-press, two oscillating heads, one of which is providedwith type-forms and the other with corresponding make-readies, incombination with mechanism, substantially as described, to oscillateboth of said heads to and from each other, and a stationary doublefrisket arranged between said heads, and through which the paper to beprinted is fed.

3. In a printing-press, two oscillatingheads. one of which is providedwith a series of type-forms and the other with correspondingmake-readies, in combination with automatic mechanism, substantially asdescribed, to oscillate said heads to and from each other, mechanism,substantially as described, to successively bring said type-forms andtheir corresponding make-readies into printing register, a stationarydouble frisket arranged between said heads, and through which the paperto be printed is fed, and inking mechanism, substantially as described,to ink said type-forms.

4. In a printing-press, the combination of heads (1 C, journaled inoscillating arms I) D, and respectively carrying type-forms andmake-readies 0 means, substantially as described, to oscillate saidheads to and from each other, shaft T, carrying the series of colorinking-rolls t, means, substantially as described, to intermittentlyrotate said shaft and heads, guides S, and adjustable guides S.

In testimony of which invention I hereunto r25 set my hand.
